<p>Objects of class <a href="Stat.html"><code>File::Stat</code></a> encapsulate common status information for <a href="../File.html"><code>File</code></a> objects. The information is recorded at the moment the <a href="Stat.html"><code>File::Stat</code></a> object is created; changes made to the file after that point will not be reflected. <a href="Stat.html"><code>File::Stat</code></a> objects are returned by <a href="../IO.html#method-i-stat"><code>IO#stat</code></a>, <a href="../File.html#method-c-stat"><code>File::stat</code></a>, <a href="../File.html#method-i-lstat"><code>File#lstat</code></a>, and <a href="../File.html#method-c-lstat"><code>File::lstat</code></a>. Many of these methods return platform-specific values, and not all values are meaningful on all systems. See also <a href="../Kernel.html#method-i-test"><code>Kernel#test</code></a>.</p>
